Ok here's my prediction something a little different. Kirkland and pj team up in the hunt for rj. After bk admits he broke into janes place and tells him that his wife was also murdered by rj and wants to find him more then anything. Pj goes with and one by one they knock down the suspect list till its at the end of the season and everyone on the list is found innocent of being rj which leaves pj then believing bk is actually been rj all along but then at the same time bk then believes Jane to actually be red John and that's how they'll leave us till season 7 what a cliff hanger it would be
